Buy Product A get 30% off each Product B

[Elizabeth]

We have 2 collections of products – A and B.

This is the coupon we need-
If someone adds a Product A to their cart, all the Products B’s each get 30% off.

This is what we have setup that’s not working-
Discount type: Percentage Discount
Discount amount: 30
Coupon cannot be used with others.
Products (OR): This is where we have all our Product B’s listed.
Excluded products: This is where we have all Product A’s since we don’t want the coupon applied to those.

At least one Product A has to be added to the cart for any Product B’s to receive the discount because it’s a BOGO type deal.

Is this possible to set up?

This requires a snippet in functions.php of your child theme.

Change Products (OR) to Products (AND) and add this snippet:

add_filter( 'woocommerce_coupon_is_valid_for_product', function( $valid, $product, $coupon, $values ) {
    $my_item_id = 123; // ID OF PRODUCT B
    $my_coupon_code = 'the-code-of-the-coupon';

    if ( $coupon->get_code() === $my_coupon_code ) {
        return $product->get_id() == $my_item_id;
    }
    return $valid;
}, 10, 4 );

Replace 123 with the id of product B and replace the-code-of-the-coupon with the actual coupon code.

Added! It worked when we tested one product.

We have 8 total product B’s and separating the item ids by commas didn’t work (got a syntax error).

Is there something I could add to the snippet for multiple products?

Thank you!

That requires a more complicated customization. Use the contact form for inquiries.
